Company and Product News

Yokogawa Electric Corporation announced the release of Dynamic Real Time Optimizer, a solution in the OpreX Asset Operations and Optimization family.  Using a combination of first principles simulation and multivariable predictive control technology, the Dynamic Real Time Optimizer software helps to optimize plant operations.

This integrated solution is based on Yokogawa's advanced process control technologies and industry knowledge and simulation technologies developed by KBC Advanced Technologies Limited, a UK-based Yokogawa subsidiary.  This solution enables plants to quickly respond to dynamically changing oil market and product market conditions and improve both productivity and profitability.

Dynamic Real Time Optimizer calculates the optimal values for plant independent variables with a high level of accuracy and was developed based on KBC's Petro-SIM process simulation platform, which includes functions for online use.  This solution acquires data through online connections to control systems and plant information management systems (PIMSs) and carries out case study simulations to generate rigorous models and calculate additional inferred properties. Based on these models and operating conditions, the optimal values are calculated by applying mathematical programming, and implemented online by the advanced control system.

Multi-unit optimization based on simulations performed using rigorous models

With large-scale applications, advanced control systems need to be able to quickly process huge amounts of data. Advanced control and optimization systems must have the processing speed needed to calculate the optimal values for such large applications.  However, commercially-available products today are only suitable for small- to medium-size applications and can only optimize the control of individual process units. Yokogawa's Platform for Advanced Control and Estimation is capable of high-speed processing and can collectively control large-scale applications across processes. Using this suite as its operating platform, Dynamic Real Time Optimizer achieves multi-unit optimization and control.  Also, as it makes use of KBC's simulation technologies, the Dynamic Real Time Optimizer software can obtain optimal values with high accuracy even with reaction processes that demonstrate non-linear characteristics.

Integrated solution with improved maintainability

The performance of advanced control and optimization systems tends to degrade over time due to changes in operating conditions, catalyst activity changes, and the aging of facilities. Dynamic Real Time Optimizer is designed to maintain advanced control performance even as a plant changes, by using an online Petro-SIM model. The structure of this solution makes it easy to maintain advanced control and optimization systems, thus enabling operators to achieve optimal performance with nearly no change in maintenance workload.

Major applications include advanced control of continuous plant processes in the oil, petrochemical, chemical, gas, and other industries.
